Childhood Never Leaves

The CMC find a book about a young filly who never wanted to grow up, wanted to have fun, and enchanted objects she played with - bed sheets, a rainbow parachute, teddy bears, a scooter, rope, wooden toys, etc. - so other fillies could enjoy the toys she played with as a filly too. The CMC think it's scary, but also ridiculous. Not believing the story, they leave, but by reading the story, magic appears from the book spreading all over Ponyville, enchanting the objects mentioned in the book. The CMC first think the objects are fun to play with, but soon get bored with them. However, the toys have other things in mind....
